Hi — love that you want to use Deftform for newsletter double opt‑in! Short status: there’s no ETA yet — the plan is to add an optional per‑form verification email (double opt‑in), but other items are scheduled first and it’s likely to arrive in an autumn release. This was previously answered by andreas_ivymayhem who said there’s no ETA yet, it’s planned and will likely be part of an autumn release. You can find that answer here: https://appsumo.com/products/deftform/questions/eta-for-e-mail-validation-thanks-1373751/
